6 Specifications
RF front-end
Frequency range: 25.5 ... 35.5 MHz (standard) or 35.0 … 45.0 MHz (option).
Crystal selected reception frequency.
Usable sensitivity: -116 dBm (0.5 μV).
Dynamic range: >60 dB.
In practice this means that a signal differing 5 kHz or more with
the buoy signal will do no harm at signal levels below -50 dBm.
